SAFETY MILK BOTTLE CONTAINER Filed Jan. 14, 1955 william H. yanumffPatented Dec. 10, 1935 UNITED STATES PATENT OFFICE l 2,023,826 SAFETYMILK BOTTLE CONTAINER Canada Application January 14, 1935, Serial No.1,815`

Z Claims.

My invention relates to holders for milk bottles, especially adapted tohousehold service and it particularly has for an object to provide asanitary, safe bottle container of a very simple and inexpensiveconstruction, one which can be sold to the customer at a low price oreven given away by milk dealers to their customers if desired.

A further object is to provide a milk bottle holder in the form of a boxor housing rigidly supported on the door jamb or frame and soconstructed that it cannot be opened from the outside save by means ofan especially constructed nkey.

A further object is to provide a milk bottle holder of the characterabove referred to in which provision is made to hold a bottle entirelyenclosed in the box or receptacle and to provide an auxiliary holder fora second bottle to be suspended beneath the box or receptacle and heldagainst removal when the box is locked.

Another object is to provide a milk bottle holder of the above indicatedcharacter in which the lock construction is such that it cannot bepicked.

Other objects will in part be obvious and in part be pointed outhereinafter.

To the attainment of the aforesaid objects and ends the invention stillfurther resides in the novel details of construction, combination andarrangement of parts, all oi which will be first fully described in thefollowing detailed description and then be particularly pointed out inthe appended claims, reference being had to the drawing, in which:-

Figure 1 is a perspective view of a doorway with my invention in place.

Figure 2 is an enlarged detail perspective view of a portion of thesame, showing the box or container open for the insertion of the milkbottles in the box and auxiliary holder respectively.

Figure 3 is a horizontal section on the line 3-3 of Figure 2.

Figure 4 is an enlarged detail sectional view of the lock.

Figure 5 is a detail elevation and part section of the key device forreleasing the bolt of the lock.

In the drawing, in which like numerals and letters of reference indicatelike parts in all the figures, I represents the outer face of a doorfrane against the side of which adjacent the door my present inventionis designed to be mounted. The box or container is preferably made ofsheet metal and consists of side walls 2,

top 3, bottom 4 and front wall 5, the major portion of the rear of thebox being an open structure, there being a shallow back wall 6 providedwith a transverse recess or depression 1 extending across the width ofthe box, one side wall being cut away, as at 8, in register with therecess 5 I for the purpose of permitting the latch tongue 23,hereinafter again referred to, to pass into the recess 'I and cooperatewith the end I5 of the latch bolt I3.

Extending from the front wall to the back wall 10 of the container isthe casing 9 of the latch device. This casing comprises a tube 9, theends of which are welded or otherwise secured to the front and backwalls 5 and 6 of the box, the said Walls being apertured in alignmentwith the in- 15 terior of the tube 9. As best shown in Figure 4, thetube 9 has indentations Ill which serve as spring stops, and it containstwo springs II and I8, respectively, separated by the stops I0.

Within the tube 9 is a ring I2 against which 20 one end of the spring II presses. When no key is in place the ring I2 is stopped by engagementwith the front wall 5, the hole 5cc of which is of slightly lessdiameter than the internal diameter of the tube 9 to serve as a stop.The hole 25 5w, however, is of suilicient diameter to permit theinsertion of the key 2l, hereinafter again referred to. Slidable withinthe tube 9 is the latch bolt I3, the bolt having a collar I4 againstwhich one end of the spring I8 presses. The latch 30 bolt I3 has anextension I5 that passes through a hole 6x in the rear wall 6 andprojects into the transverse recess I in order to cooperate with thetongue 23. The latch bolt I3 has a neck I6 and a tapered head I'I. Thediameter of the head 35 I I does not exceed that of the internaldiameter of the ring I2.

I9 designates the supporting plate which has a ilange I9 to overlie theadjacent wall of the container when the container is in the closed or 40locked position. The plate I9 is provided with keyhole slots 20 extendedin an inclined position so as to cooperate with the face of the door 33to hold the container on the door frame. The slots 20 also cooperatewith the -screws 2| by means of 45 which the plate I9 is held againstthe side face of the door frame I, as best shown in Figure 2.

23 is the latching tongue which is projected from the face of the plateI9 adjacent the door. 'Ihe tongue 23 is of a somewhat resilient nature50 and has a hole 22 for the reception of the latching end, I5, of thelatch bolt I3 when the box is swung inwardly to the closed position.

24 are hinges, which hinge the box to the plate I9, and 25 is a springclip, preferably stamped 55 box or receptacle and also for the auxiliaryreceiver.

The key by which the box may be unlocked consists of a tube 21 having afinger button 28 at one end, the tube and butto-n slidably receiving arod 29, one end of which is Ysplit at 20 to constitute resilient tongs30. A spring 32 is carried on the rod 29, and at the outer end the rodis provided with a thumb button 3|. The spring 32 serves to push thetube 21 over the split end of the tongs 30 to hold the same togetherretracted within the tube 21. It is to be understood that the rod 29adjacent the slotted end 30 is of tubular form. The free ends of thetongs 30 are slightly inwardly bent to t over the head I1 of the latchbolt.

In order to unlock the box the key is inserted through the opening 5x.As the key is inserted through the opening 5r the end of the tube 21engages the ring I2 and pushes itinwardly. At the same time the operatordraws the members 28 and 3| together to allow the tongs 30 to split andpass over the head I1. Y The tube 21, as the operator releases it,causes the tongs to grasp the head I1. This grasping action is effectedby the spring 32 pressing against the button 2B to force the tube 21over the split ends. The key now havingA been secured in graspingposition to the head I1, the operator simply pulls on the head 3I, whichwithdraws the end I5 of the bolt and releases the box from the latchingtongue 23 so that the box may be swung to the open position for theinsertion or removal of the milk bottles. Y

The ange I 9m, hereinbefore referred to, allows for the thickness of thehinges and screw heads, etc., and prevents a space being left betweenthe hinge side of the box and the plate I9 when the` box is swung to theclosed position, thus making it impossible to get an instrument betweenthe box and the plate for the purpose of bending the latching tongueaway from the latch bolt.

' In order that the operator may not inadvertently leave the key in thetube 9 after he has released it from the head I 1, I have provided thespring I I and collar I2, hereinbefore referred to. As soon as theoperator releases the tongs 5 30 by pulling back on the button 29, whileholding the button 3| against movement, the spring II will tend to forcethe key out. Should the operator let go of the key it will be ejected bythe action of the spring II. 10

From the foregoing description, taken in connection with theaccompanying drawing, it is thought that the complete construction,operation and advantages of my invention will be clear to those skilledin the art. l5
